What a mobile app costs: the nine things that decide the price

Why two quotes for the same app can differ so widely, the nine things that drive the price, what a low quote leaves out, and how to brief so quotes can be compared.

Ask five companies what an app costs and the answers will have little in common. One has priced six screens that show information. Another has priced accounts, payments, notifications, an admin panel and the server that makes them work. Both called it "an app".

The price follows from a short list of decisions. Make them, write them down, and the quotes you receive start to describe the same thing.

01The nine things that set the price

  1. Platforms. iPhone only, Android only, or both. Both can be one shared codebase or two separate apps.
  2. Native or cross-platform. Cross-platform is cheaper for apps that are mostly screens and data. Native costs more and suits apps that lean hard on the device.
  3. Number of distinct screens and flows. Twenty screens built from four patterns cost far less than twenty unlike screens.
  4. Accounts. Sign-up, login, password reset, profiles and roles are a project in themselves.
  5. The backend. The server, database and APIs behind the app are often half the work, and they are invisible in a mock-up.
  6. Connections. Payments, maps, messaging, an ERP or CRM: each link to another system is a piece of work and a thing that can fail.
  7. Device features. Camera, location, Bluetooth, background activity and offline use each add design, code and testing.
  8. Design. Standard platform components adapted to your brand, or an interface drawn from nothing with custom motion.
  9. Standards. Security, accessibility, performance on older phones and proper testing take real time when done properly.

02What is usually left out of a low quote

  • The backend, or all but the simplest version of it
  • An admin panel for your own team
  • Testing on a real range of phones, not two
  • Store submission, and the back-and-forth when a store asks for changes
  • Analytics and crash reporting
  • Updates when Apple and Google release new versions each year

A quote is only cheap if it covers what you assumed it covered. Ask for the list of what is not included.

03The cost after launch

An app is never finished on launch day. It needs hosting for its backend, updates when phone software changes, fixes for the faults real users find, and store fees. Ask for the monthly figure and what it includes before you sign, and budget for it for as long as the app is live.

An app that nobody maintains stops working, usually within a couple of years, when a platform update breaks something it depends on.

04How to get quotes you can compare

  1. Write one page: who uses the app, the three things they must be able to do, and what would make it a success.
  2. List the platforms and say whether people need accounts.
  3. List every other system it must talk to.
  4. Ask each company for a written scope, a price, a timeline and the monthly cost after launch.
  5. Ask what they would leave out of a first version, and why.

05Spending less without regretting it

  • Launch on one platform, the one most of your users have, and add the other when the app has proved itself.
  • Ship the three things the app must do well. Leave the rest for the second version.
  • Use standard platform components instead of a fully custom interface.
  • Ask first whether a well-built web app would do. It often would, and it costs less to build and to run.

In short

  • App prices differ because the scopes differ. The backend, accounts and connections are where most of the difference hides.
  • Platforms, native or cross-platform, screens, accounts, backend, connections, device features, design and standards set the price.
  • Ask every company what is not included and what the app costs each month after launch.
  • A one-page brief makes quotes comparable.
  • One platform and three things done well is a sound first version.

Questions

Why will nobody give me a price for an app without a conversation?

Because the price depends on the nine decisions above, and most of them are not visible in a description like "an app for my business". A company that quotes without asking is guessing, and the guess is usually corrected later, upward.

Is it cheaper to build an app in India?

Engineering rates are lower than in the United States or Western Europe, so the same scope usually costs less. The scope still decides the price, and a low rate does not rescue an unclear brief.

Is cross-platform always cheaper than native?

Usually, for apps that are mostly screens and data, because one codebase serves both stores. It stops being cheaper when the app needs deep device features, which then have to be written separately for each platform anyway.

Do I need an app, or would a website do?

An app earns its place when people will use it often and it does something a website cannot: notifications, offline use, the camera, a daily habit. If not, a web app is cheaper to build, run and change.

How does Quantum Beetle price an app?

We write the specification first, including the backend, then give a clear quote against it, with the monthly cost after launch stated alongside. A small business gets a small, clear scope.
